The laws vary from place to place. But in nearly every jurisdiction the first question is whether your wife can make her own decisions. If so then she can live wherever she likes. However the context of your question suggests that she cannot.

If she can't make her own decisions then has someone been appointed as her guardian? The guardian's rights operate when your wife can't give consent. If there is no guardian then it's normally the spouse who is the decision maker, so your rights would supersede the stepdaughter's permission.

So unless your wife appointed your daughter as her guardian, your daughter will have to go to a court or tribunal and show them that it's strongly in your wife's interests to be moved.

All of them, unless you are incapable or have signed your rights away, as the spouse you would usually have the final decision in all treatment issues if your wife cannot answer for herself. (and has not stated a written preference to a legal or medical professional.)
